Memory 10 - The Sentinel, Part II

Full Sync - Do not be detected while you search for the prisoners. Read the walkthrough below for the full details.</div>

Approach the marker to start the mission. After a brief convo with the apprentice, Ezio needs to find both captured allies undetected.

To achieve Full Sync, you'll need to use all the resources you can find. Find the nearest Bomb Crafting station and make some Impact Splinter Bombs, you'll need them.

Approach the location of the nearest ally (to the east) and you'll spot a group of Mercenaries. Hire them and let them fight off the Byzantine guards (the ones marked as red dots). As they battle, make your way into the area near the ally (eliminate the walking guards first before they spot you) and then approach the ally.

With the first ally freed, find the second ally to the north. The ally is guarded by two Byzantine guards near the tower. Equip a Splinter Bomb and toss it at them to clear them out. Now approach the ally and speak to him to get Full Sync.

Once that's done, run back to the Assassin's HQ to trigger a cutscene with the Sentinel. Chase after the Sentinel and the apprentice will do the rest. Mission complete.
